Solution: Minimum String Length After Removing Substrings
Explore how to use a stack to iteratively remove specific substrings from a string. This lesson helps you understand how to apply stack data structures to efficiently reduce a string by eliminating pairs like 'AB' and 'CD', resulting in the shortest possible length after all removals. You will learn to implement this approach and analyze its time and space complexity.
We'll cover the following...
Statement
You are given a string, s, containing only uppercase English letters. You can perform operations on this string where, in each operation, you remove any occurrence of the substrings "AB" or "CD" from s.
Your task is to return the shortest string length after applying all possible operations.
Note: After each removal, the string joins back together, potentially creating new occurrences of "AB" or "CD" that can also be removed.
Constraints:
